Abstract:
A 55-year-old man developed deep venous thrombosis and inferior vena cava (IVC) thrombosis 7 years earlier and was treated by placement of a permanent IVC filter. One week ago, he was admitted with bilateral lower limb swelling and pain. Digital subtraction angiography showed a filling defect above the original filter. A retrievable Tulip filter was placed and catheter-directed thrombolysis was performed. Six days later, the patient experienced sudden, persistent upper right abdominal pain, and a computed tomography scan revealed the formation of retroperitoneal hematoma. Symptomatic treatments were administered, and the hematoma gradually resolved during follow-up.
